MACHINE FOR FLESHING AND/OR SCRAPING HIDES Luis Alberti, Buenos Aires, Argentina Application June 10, 1948, Serial N0. 32,087 In Argentina March 22, 1948 4 Claims.

The invention relates to a new type of machine destined for fleshing and/or scraping hides generally which offers many advantages in comparison with machines which are now in use for the same purpose.

Machines which presently are used for fleshing or scraping hides are stationary and each one performs only one operation, as their construction does not enable changing the mechanisms for performing both operations, that of fleshing and that of scraping with the same machine. On the other hand present machines for fleshing hides perform the operation by gaging uniformly the thickness of the hide which is not in accordance with the principles of rationality, as fleshing a hide at a determined thickness means wasting a percentage thereof.

It must be understood that the hide, principally that of cattle, when fleshed carefully by hand with a knife, will show a great variation in thickness; it is then easy to suppose what will happen when fleshing is done with a stable machine. Many surfaces without flesh are cut away uselessly due to uniformity .of cutting. Considering these disadvantages, the present movable machine has been conceived which, as it adapts itself partially to relatively small surfaces, can flesh different hides with a minimum percentage of waste. On the other hand the substantial difference between both mechanisms of which the first one is very heavy, complicated and expensive, whereas the second one is light, easy and economical, does not give occasion to doubt about its adoption as a highly practical machine. By replacing only the fleshing cylinder by a scraping cylinder, a second working operation will be performed which present machines cannot do.

On the other hand an ingenious fastening device will contribute So that the handling of said machine does not cause weariness to the worker, as its disposition is devised in such a way that the machine may be used during lengthy and continuous periods.

For the purpose of explaining quite clearly the nature of the invention and the manner in which it can be carried into practice, an example thereof will be described hereafter with the help of the accompanying drawings.

Figure 1 shows the new machines provided with a fleshing cylinder, seen laterally.

Figure 2 shows the same machine seen in front.

Figure 3 shows a partial view of a scraping cylinder, which element placed into the same machine and instead of the fleshing cylinder will perform another manufacturing process.

Figure 4 shows the device which fastens the machine, seen laterally.

Figure 5 shows a part of the fastening device, seen in front.

Figures 6, 7 and 8 show different positions of the fastening device and the machine.

Body I of the machine will be provided with a U-shaped fork 2 the extremes of which will be inserted into pins 3 fixed to the body so that a rocking movement may be given to the machine. Body I carries the fleshing or scraping cylinder 4 (see Figure 3) in both cases shaft 5 seated in bearings 6 will be duly attached to the assembly.

An electric motor I which is situated at the posterior and inner part of body I will transmit the necessary rotation to cylinder 4 by means of pulleys 8 and 9 and belt I0.

0n the other hand at the extremes of shaft 5 there will be provided pillows II having a well arranged surface so that, by means thereof, the worker in charge of the machine may guide it with both hands over the surface of the hide to be treated.

At the center of fork 2 which corresponds to the back thereof an element will be provided which has the value of a hinge; one of the blades thereof, viz. that indicated by reference I2, will be attached laterally to fork 2 by means of screws or rivets I3; the opposite blade I4 which is free will have a perforation I5. On the other .hand axle I6 of the hinge which extends outsides thereof will carry an element I1 which is provided with two cams I8 and I9 and which besides will have an arm 20 curved more or less in an angle of the extreme of which will end at a ball 2| of determined diameter and weight.

Hinge blade I4 as well as element U will have an independent movement, but both will turn round axle I6 of the hinge. As to cams I8 and I9 it may be mentioned that both are substantially equidistanced from axle I6, and as one of them, viz. that indicated by reference I8, will exceed extreme 22 of hinge blade I4 when element I I is turned about the axle, as a result thereof said cam I8 will touch against plane 23 of said hinge blade I4; whereas, when said element I1 is turned in an opposite sense, opposed cam I9 will touch plane 24 of hinge blade I 4.

At the front part which corresponds to the superior plane of body I of the machine, and, coinciding in direction with the center of the hinge, there will be put a forked pole 25 which is fixed to body I. In the axle 26 thereof a lever 21 will be maintained, the body of which will enable lodging there in part of extreme 30' of hinge blade I4.

Operation is as follows: Figure 1 shows-the pending machine in working position, viz. cylinder 4 is placed upon work plane 31'. Parting" therefrom and supposing that the p'erson incharge of the machine wishes to hayelit outaofi contact with work plane 3!, counterweight -2l must be in the shown position, which Ine'ans'to say that the action of counterweight 2|, due to gravity, will cause the-cam19 to't'ouch the-inferior plane 2d of hinge blade. When taking colateral handles ll and'liftin'g machine which will turn upon pins 3, hinge blade M will slide along lever 21 and will drop'into one of'incisions 2-9 of said lever 21. In this'fashion theheight of the machine will be perfectly assured-and it will be suspended at cable '32, as 'maybe seen from Figure 6.

When the worker wishes to put the machine upon work plane 3|, he will have to turn forwards element [1 which carries counterweight 2|. In this case cam 18 will-touch plane 23 of hinge blade i l (see Figure 7), whereby, lifting the machine a little and turning alwaysupon pins 3, hinge blade [6 may be withdrawn from any one of incisions 29, as'may' be seen in Figure 8. In these conditions the machine'canbe-put freely upon work plane 3|. For machines-of a certain size and weight a series of orifices 33 amply distanced between one another may be provided, wherein fastening pins 3' to fork 2 can be put for the only purpose that theelevation plane of the machine results comfortable for the worker. As cable .32 may be provided with rotary unions or simply with knotted extremes action of the machine can-b effected in all angles and planes'which are desired.

When the machine is suspended as shown'in Figure 1 and part of a hide to flee-fleshed or scraped isput upon the work table, whereas the rest of the hide is held in place,-securedbythe abdomen of the worker at the edge of the table or by any other adequate mechanical fastening means, treatment thereof will bebegunprevdlving rapidly the cylinder upon thesurface it rests upon and displacing the machine slowlythereupon in different directions whereby in each case the desired effect will be had;

Iclaim:

1. A portable machine for the fleshing and scraping of hides, which comprises: A working cylinder pivoted for rotation in a supporting frame at the front end of said machine; a U- shaped rocking fork pivoted at one end thereof to said supporting frame,.-and..suspended at the other endfrom an elevated gpo'siti'on by means of a relatively flexible suspension means; a hinge vpivotally supported from said U-shaped rocking fork by a pivot pin, said pivot pin being positioned at approximately the center of said hinge, said hinge having a blade which extends freely toward said supporting frame and working cylinder, and said blade being provided with an elongated aperture positioned therein; an element including an arm doubled approximately at an angle of 90 degrees, said element being pivoted at said pivot pin at which said hinge is pivoted, but at a point exterior of said hinge; a pair of cams supported on said elementincluding said doubled arm, one ofsaid cams being positioned on either side'ofsaidpivot'pin and at an equal distance therefrom; a pole disposed at the front of said machine on"- the upper surface of said supporting frame, sai'd'pole' being provided at its end remote'from said supporting frame with a supporting fork; and'adever of substantially rectangular cross-section seated at one of its ends in said supporting fork, saidlever then extending through said elongated aperture in said blade, said lever being provided" with a series of incisions in its lower e'dge'portion adjacent the end thereof supported fromsaid pole by means of said supporting fork, said-incisions being adapted to seat and retainsaid blade of said hinge which extends'toward" said supporting frame and said Working cylinder.
